Definitions

  • the invention relates to a plate storage arrangement and in particular to a device for carrying an upright object, e.g. an art object, a company logo or a monument, of the type described in the preamble of claim 1.
  • an upright object e.g. an art object, a company logo or a monument
  • Such devices are known in particular from monuments or art objects erected in parks, in many cases the base which actually supports the object is fastened on a generously dimensioned base in order to give the object a suitable exposed altitude.
  • a pivot bearing arrangement according to the preamble of claim 1 is known from FR-A-2 404 163.
  • This has a lower stone table and an upper rotatable stone table, on which a centering mandrel is arranged, which projects into a recess of the lower table and is fastened there.
  • the upper table is rotatably supported by roller bearings on the centering mandrel. Even the relatively low friction in the rolling bearings leads to a relatively early standstill of the top plate if it is not constantly driven.
  • the friction losses between the plates should be reduced to a minimum.
  • the advantage of the arrangement according to the invention is, in particular, that the friction between the base plate, which is floating on a liquid film and rotatable about a vertical axis, and the base plate is extremely low. For this reason, e.g. a base plate carrying an object even under the action of low forces, e.g. light bumping by an observer or any irregularities in the direction of the liquid supply, begin to rotate about a vertical axis.
  • This unusual effect for art or similar objects draws the attention of passers-by to the exhibited object, who might have disregarded a static object.
  • the base plate has a recess which opens towards its top and which receives a centering projection which projects from the underside of the base plate.
  • the recess is provided with at least one liquid supply which presses into a gap between the recess and the centering projection.
  • the plate arrangement so that the base plate is a has a recess opening towards its underside, which receives a centering projection protruding from the upper side of the base plate, the base plate being provided with at least one liquid which presses liquid into a gap between the recess and the centering projection.
  • the surfaces of the base plate and the base plate which would come to lie on one another without a liquid film, are ground flat, thereby making it possible to produce and maintain a gap filled with a liquid film in the entire region of these surfaces.
  • the centering projection or the recess are each arranged centrally on the base plate or the base plate, as a result of which, when an object is set up, the center of gravity of which should also be centered above the base plate, a very even distribution of force on the liquid film comes about and even with eccentric arrangement of the above-mentioned center of gravity there are no moments that weaken the liquid film too strongly.
  • a circular design of the base plate can help to avoid unbalance during its rotational movement.
  • an at least partially spherical cap-shaped body as the centering projection and one that is essentially a perfect fit receiving, at least partially spherical cap-shaped recess provided.
  • the gap between the two spherical cap-shaped components can be flowed through and filled very uniformly by the liquid film due to its hydrodynamically favorable properties, a favorable lateral centering also being achieved.
  • an at least partially cylindrical body is provided as the centering device and an at least partially cylindrical recess that essentially accommodates it with a precise fit.
  • Such a configuration of the recess or the centering projection is very simple and inexpensive to manufacture and offers optimal centering of the base plate.
  • the liquid supply is arranged centrally in the recess in alignment with the axis of rotation of the base plate. In this way it can be achieved that the centering projection in the recess is evenly flowed around and that there is no excessive narrowing of the liquid film even with very eccentrically loaded base plates.
  • the arrangement according to the present invention is designed such that the liquid supply is arranged in the recess in such a way that the liquid jet emerging therefrom strikes a lower surface of the centering projection of the base plate.
  • the base plate is very easy to move due to its low friction with the base plate, it can be ensured, for example, by a simple oblique arrangement of the liquid supply line that the object to be carried rotates uniformly together with the base plate.
  • the jets emerging from the liquid feeds are directed, at least in part, symmetrically onto the cylindrical surface of the cylindrical centering projection.
  • the liquid supply can advantageously consist of at least one hole in the base plate, which enables an inexpensive and simple manufacture of this supply.
  • the plate bearing arrangement according to the invention is characterized in that at least two nozzles in the upper ends of the tubes or the bores direct their emerging liquid jets at an angle to one another and in each case both obliquely against a surface of the centering projection or the calculation, the It is possible to provide the liquid supply of each nozzle with a shut-off valve and to control the shut-off valves via a common switching arrangement so that they open and close alternately.
  • a tube or a bore of the liquid supply is equipped at its upper end with a periodically pivotable nozzle, whereby a weakening of the base plate by a larger number of bores can be avoided at the same time.
  • the base plate of the arrangement according to the invention is preferably equipped with a fastening device for an object to be carried.
  • the liquid supply through the bores or tubes into the recess can preferably be carried out by a pump which pumps the liquid from a reservoir under pressure into the tubes or bores and thus into the recess.
  • the plate arrangement is characterized in that the base plate has at least one through hole through which liquid can reach its top from its underside in order to exit there.
  • the arrangement is thus used as a fountain, which, since water is usually used as the liquid, is easy to implement and structurally inexpensive.
  • the arrangement can be designed so that a mouth of a through hole at the top of the base plate is arranged so that the direction of the force generated by the emerging liquid does not go through the axis of rotation of the base plate, so that a moment about the axis of rotation arises.
  • the base plate is equipped with a continuous rotary drive, without further design measures being necessary to produce the rotation.
  • the single figure shows a central section through an arrangement according to the invention together with a plan shown below.
  • the top view and the central section according to the figure represent the arrangement of the base plate 1 and the base plate 2 of the plate bearing arrangement according to the invention.
  • a centering projection 3 is formed centrally on the underside of the base plate 2, which in this exemplary embodiment has a spherical cap-shaped design. This centering projection 3 is received in a recess on the upper side of the base plate 1, which in its upper region is also designed to fit the centering projection 3 in the form of a spherical cap, while in its lower region there remains a cylindrical space for receiving the liquid to be supplied.
  • the liquid supply can be connected via a pump P to a reservoir 2 for the liquid, preferably water.
  • the liquid from the reservoir R is below Pressure is pumped through the liquid supply 5 into the free space of the recess 4 until the pressure in the recess 4 has increased enough to raise the base plate 2 with the object (not shown) standing thereon so far that the liquid passes through between the spherical spherical bodies and gap can flow between the facing surfaces of the base plate 1 and the base plate 2, thereby forming a thin film of liquid.
